Review Change StackReview Change Stack

Walkthrough

The changes add repository guidance for packaging and launching third-party harness adapters. They define dependency, executable-resolution, discovery, transport, authentication, and validation checks.

Changes

Adapter integration guidance

Layer / File(s) Summary
Packaged adapter validation
.agents/skills/contribute-adapter/SKILL.md
The guidance requires isolated packaged-artifact installation, dependency verification, platform-wide executable-resolution tests, exact launch semantics, and exclusion of tool-version-only reference changes.
Upstream harness integration
skills/nemo-fabric-build-adapter/SKILL.md
The guidance covers upstream release and runtime checks, dependency failure classification, discovery controls, authenticated transport boundaries, and validation for stateful, external, and authenticated connections.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Other

Merge Risk: 🟡 Moderate · up to d838d

The new guidance should state whether configured upstream URLs are trusted operator configuration or require an origin or network policy. Without that decision, lower-trust configuration could direct credentialed requests to an unauthorized endpoint.

- Around line 124-126: Update the adapter guidance for credentialed upstream
URLs to require an explicit decision on whether base_url is trusted operator
configuration. Permit configured custom-provider origins without imposing a
fixed allowlist, but require adapters to enforce and test an origin or network
policy before sending credentials whenever lower-trust input can control
base_url.
